dnsctl

dnsctl 是一个简单的命令行工具用于控制 CoreDNS 的 etcdhost 插件，从而实现对 etcd 内 hosts 文件一处修改全局生效。

一、配置

默认情况下 dnsctl 读取 $HOME/.dnsctl.yaml 配置来链接 etcd 集群，配置样例如下:

# etcd 中 etcdhosts 插件的 key
dnskey: /etcdhosts
# etcd 集群配置
etcd:
  cert: /etc/etcd/ssl/etcd.pem
  key: /etc/etcd/ssl/etcd-key.pem
  ca: /etc/etcd/ssl/etcd-root-ca.pem
  endpoints:
    - https://172.16.10.11:2379
    - https://172.16.10.12:2379
    - https://172.16.10.13:2379

可通过 dnsctl config 命令查看样例配置

二、使用
